For a positive integer c, a c-vertex-ranking of a graph G = (V,E) is a labeling of the vertices of G with integers such that, for any label i, deletion of all vertices with labels i leaves connected components, each having at most c vertices with label i. The c-vertex-ranking problem is to find a c-vertex-ranking of a given graph using the minimum number of ranks. In this paper we give an optimal parallel algorithm for solving the c-vertex-ranking problem on trees in O(log2n) time using linear number of operations on the EREW PRAM model.
